REXELite

REXELite allows to
search
for a suite of waveforms compatible with a target spectrum, generated
according to
EUROCODE 8. Read the PDF tutorial

How it works

REXELite is
an
application which allows to search for combinations of
seven 1- or 2-components strong motion records, compatible in average
with a specified code spectrum. More specifically, REXELite:

automatically builds code spectra for any limit state
according to Eurocode 8 (CEN 2003) spectra and the new Italian building
code spectra (CS.LL.PP. 2008, 2009)

finds the set of seven records having the most
similar spectral shape with respect to that of the code, and whose
average also matches the target spectrum in a user-specified period
range and with the desired tolerance.

The records are extracted according to specific features, in
terms of
magnitude, distance and soil conditions selected by the user. The set
of accelerograms of the combination (see Figure for an
example) may
include unscaled (original) or amplitude-scaled records and may be used
for code-compliant non-linear time history analyses of structures.

REXELite Working group

REXELite is a simplified online version
of the
computer program REXEL
(Iervolino et al., 2009), developed by Iunio Iervolino and Carmine
Galasso, of the University Federico II of Napoli, for selection of
ground motion suites for code-based seismic structural analyses.
REXELite was developed within the INGV-DPC
S4 project
funded by the National Department of Civil Protection, coordinated by
Francesca Pacor (INGV, Milano) and Roberto Paolucci (Politecnico di
Milano), in cooperation with RELUIS.
The online implementation was made by Andrea Spinelli of IMTEAM.
